This report was released for the 2006 Covering Kids & Families Back-to-School Campaign, a national effort to enroll eligible children in public coverage programs during the back-to-school season.  This initiative is sponsored by the Robert Wood Johnson Foundation.  The research in this report presents the the number of uninsured children, publicly insured children and privately insured children in the U.S. and by state in 2003-2004, using data from the CPS, compared to the same information for 1997-1998. This comparison documents coverage patterns before and after the implementation of the State Children’s Health Insurance Program (SCHIP).  August 2006.
